Folkung

However, many of these political opponents were also said to have been descendants of Jarl Folke the Fat (from the House of Bjälbo), who lived before the family became royal.

Hence, in the 17th century, the whole family, then already extinct and without any established name, became known as the House of Folkung (Folkungaätten in Swedish).

Later research, though, showed that the political Folkungs were not just descendants of Jarl Folke—instead, they belonged to different Swedish noble families, united by the ambition to fight against a central ruler of Sweden.

According to one theory, Folkungs wanted to keep the old "freedom" of the petty kingdoms, including the election of kings, and to retain local power in their own control.
